View Patent ↗The present invention relates to a micro-abrasion device comprising: a first reservoir intended to contain a powder to be sprayed onto a surface that is to be treated, a second reservoir intended to collect the used powder, a handpiece designed to be applied against the surface that is to be treated. This device comprises a removable cartridge ( 5 ) that can be fitted onto the device and removed independently of the handpiece and comprising the first and the second reservoirs.
1. Micro-abrasion device comprising:
a base station;
a handpiece configured to spray a powder onto skin;
a flexible supply pipe configured to supply powder from the base station to the handpiece;
a flexible return pipe configured to return powder from the handpiece to the base station; and
a removable cartridge configured to be fitted onto the base station and removed therefrom, the cartridge comprising:
a first reservoir containing a powder to be supplied to the handpiece via said flexible supply pipe, and
a second reservoir configured to collect powder returning from the handpiece via said flexible return pipe.
2. A device according to claim 1 , wherein the first and second reservoirs are connected together non-removably within the cartridge.
3. A device according to claim 1 , characterized in that the first and second reservoirs form two compartments within a body of the cartridge.
4. A device according to claim 1 , wherein the first and the second reservoirs are contiguous within the cartridge.
5. A device according to claim 4 , wherein the first and second reservoirs include a common wall.
6. A device according to claim 1 , wherein the first reservoir includes a longitudinal axis and wherein a section of the first reservoir transverse to the longitudinal axis narrows toward a bottom of the first reservoir.
7. A device according to claim 1 , wherein the first reservoir comprises a tube including an open upper end.
8. A device according to claim 7 , wherein the tube comprises a lateral orifice allowing the powder to be supplied to the handpiece to enter the tube.
9. A device according to claim 1 , wherein the first reservoir comprises an air intake on a side wall of the first reservoir.
10. A device according to claim 1 , wherein the cartridge comprises a puncturable seal configured to close off a connection endpiece configured to connect the first reservoir to the base station.
11. A device according to claim 10 , wherein the base station comprises a housing configured to accept the cartridge and wherein the housing is configured to prevent the cartridge from being inserted in the housing in anything other than a determined position.
12. A device according to claim 1 , wherein the cartridge comprises a moulded plastic body and a closure cap attached to the body.
13. A device according to claim 1 , wherein the base station comprises a housing configured to accommodate the cartridge and wherein the housing is provided with a sealing piece made of elastomer.
14. A device according to claim 1 , wherein the cartridge comprises endpieces in communication with the first and second reservoirs and wherein the sealing piece is configured to press in a sealed manner against the endpieces of the cartridge.
15. A device according to claim 1 , wherein the powder is based on cereal flour.
16. A device according to claim 14 , wherein the endpieces are made by molding as a single piece with a body of the cartridge.
17. A device according to claim 1 , wherein the base station comprises a vacuum pump.
18. A device according to claim 1 , wherein the base station comprises a first housing configured to accommodate the cartridge and around the first housing a second housing of annular shape configured to house the flexible supply and return pipes was inserted therefore connecting the handpiece to the base station.
19. A device according to claim 18 , further comprising a hinged lid configured to close the first housing.
20. A device according to claim 18 , further comprising a boss provided with the first housing, the boss comprising a depression configured to accept the handpiece when not in use.
21. A device according to claim 20 , wherein the boss comprises third and forth housings configured to accommodate handpieces configured to be fitted to a body of the handpiece.
